condenser by means of either a rotary 01' a reciprocating condensate pump. The rotary pump has a nuinber ofxadvantageous fea tures which render it-moredesirable than the ordinary reciprocating pump. One objection however, is that the rotary condensate submergencei- This is sometimes diflicult to. accomplish, especially in marine installations-"where thehead room is'material1y limited. In addition to this, the pumpiis necessarily located in an almost inaccessible place and consequentlyit is difficult to give 1 it proper care and attention and to repair it in case of accident.

Anobject of this invention is to provide a new and improved apparatus forlwithjdrawother liquids ing water ofv condensation or from-a condenser, V V v A further object is top'roduce a new and improved condenserinstallation in which the condensate pump'may'beiloeated in any suitable place and yet have the proper sub mergence.

These and other objects which will be,

made apparent throughout the'further de scriptionfot' my invention'are attained by means of apparatus embodying thefeatures of my invention herein described, and llllIS- trated infthe drawing accompanying and forming Ea part hereof. r A
